Nanoparticle based Flu vaccine shows promise in pig study

By /

An Ohio research group tested the efficacy of inactivated Swine Influenza virus (SwlV) encapsulated in 200–300 nm diameter PLGA (poly lactic co-glycolic acid) microspheres. Pigs were immunized twice intranasaly.  While control pigs had fever for four days, treated pigs showed no clinical flu symptoms.
